GAS-FURNACE.

SPECIFICATION forming part of# Letters Patent N0. 499,157, dated. J' une 6, 1893.

Application filed October 23, 1891. Serial No, 409,627. (No model.)

To all whom t may concerm Be it known thatl, WILLIAM T. BATE, a citizen of the United States, residing at Conshohocken, in the county of' Montgomery'and` My present inventionrelates particularly to' the producin gf urnaee and to the convertin g or v fixing chambers, and has for its object to provide means for cheaply and economically heat ing air to be used in gas making or for metallurgical purposes,and incidentally to protect the furnaces by passing through the walls thereof volumes of air to be heated whereby heat is absorbed and carried off and the walls'are protected and prevented from being damaged by overheating.

To these ends the invention consists in forming in the Walls of the producing or converting furnaces or inthe partitions between the chambers thereof, airpassages or flues through which air is forced from the outside to be heated, as will be hereinafter fully described.

In the accompanying drawings which illustrate my invention and form a part of this specification, Figure 1 represents a plan'view of the producer and converter, with the pipe connection between the same. Figl 2 represents a vertical section on the line @-5, in Figs. 1 and 3; and Fig. 3 is a horizontal section on the plane indicated by the broken line c-d, in Fig. 2.

1 designates the gas-producer which co`mprises twin-chambers, 3, 3, separated by a dividing wall or partition, 2, each of which chambers is provided with a grate, and with a door, 6, opposite the grate for .the withdrawal of non-combustible residue, with openings near the top for the introduction of gasproducing materials, and with suitable valves for controlling the escape of gas.

47 designates the purifier, which also comprises two chambers or compartments, 46, 48, divided by a partition wall, 50, in the lower part of which is an arched opening, 49, which forms a communicating passage between the two chambers through lwhich the gas passes from the chamber 46 into the chamber 48.

The producing furnaces and the purifier are connected at their upper parts byl a sysl tem'of valved pipes, 30, through which the '102,.for the reception'of'coke, with a door, 19

opposite the grate forkthe withdrawal of ashes, cinders, dsc., with an opening at the top which is closed by a plate and retort fastening, 97,

and with tuyere opening, 106, below thegrate. d The chamber 48, is also provided at the bot'- tom with a door 20 through which it is cleaned out, with an outlet passage near the top by which it is connected with the washer, and with an opening in the top closed by a valve, 100, which is operatedby a lever, 101.

As above indicated the subject matter of the present application comprehends a construction of the producing and converting furnaces whereby provision is Amade for utilizing the waste heat of the furnaces for heating air to be used in the manufacture of gas, or for other`purposes, such as general heating, metallurgical operations, dac., and whereby the lsurplus heat is abstracted and drawn off from the walls of the furnaces and the latter protected from damage by overheating. In the partition wall, 2, between the producing chambers 3, 3, and in the partition, 50, between the converting and fixing chambers, 46, 48, are horizontal pipes or fues, 51, arranged in vertical series, as shown in Fig. 1, through which fines, the air to be heated is passed and which in itspassage absorbs and carries o ff the surplus heat from the Walls, theh'eated air drawn off being replaced by cold air drawn in from the outside, whereby the wall is kept comparatively cool and is prevented from being overheated and damaged. The pipes 5l are flanged at their ends, so as to bind and hold the vwalls and thereby strengthen.

Each horizontal fiue is connected at both ends with D-shaped vertical pipes or fines, 7, one having an inlet near the bottom and the opposite one having an outlet near the top.

lets for conveying the heated air to the point claimor structure Where it is to be used, and when more than a natural draft is required, fans or blowers (not shown) may be applied to the inlets and the circulation thereby accelerated.

The air may be passed through the heating lines in either direction, especially when forced by a fan or blower, but in order to utilize the buoyancy of t'heheated air in producing a natural draft, the cold air should be admitted at the bottom and the heated air drawn oif-atthe top.

The operation of my invention will bereadilyunderstood in connection with theabove description and is as follows: The cold air entering at the bottom of' the flues passes through the same and upward to4 the` exit,

from which it may be conductedby meanstof Y the presence of two witnesses.

pipes to the place where it is to beused, either as a blast or for heating purposes. These fines, being madeof metal, have the additional advantage of strengthening the furnace walls and rendering them more durable. Also, while I show and describe my invention in connection with a gas furnace, it is to be understood that it is applicable to furnaces generally without regard to their use or purpose.

Having now described my invent1on,I

I. In a gas producing furnace embracing a l generating and firing chamber, the combination with the partition wall thereof, of the air `fines consisting of metallic pipes embedded yin the walls, the said pipes being fianged at the ends which embrace the outer walls of the furnace, to strengthen and hold the same,

substantially as specified.

2. The combination with the'metallic ilues embedded in and extending throughthe Walls `of the furnace, of,V thev vertical D.shaped dues having their. open sides communicating with the open ends of` the `air lines, andl provided `with inlet and` outlet air passages,substantially as specified.

In testimony whereof I alx my signature in WILLIAM T. BATE. Vitnesses:
